A set of genes in the posterior end of developing mouse embryos shows oscillatory expression, thereby regulating periodic somite segmentation. Although the mechanism for generating oscillation has extensively been clarified, what regulates the oscillation period is still unclear. We attempted to elongate the oscillation period by increasing the time to transcribe Hes7 in this research. We generated knock-in mice, in which a large intron was inserted into Hes7 3′UTR. The exogenous intron was unexpectedly not properly spliced out and the transcripts were prematurely terminated. Consequently, Hes7 mRNA lost its 3′UTR, thereby reducing the amount of Hes7 protein. Oscillation was damped in the knock-in embryos and periodic somite segmentation does not occur properly. Thus, we demonstrated that Hes7 3′UTR is essential to accumulate adequate amounts of Hes7 protein for the somite segmentation clock that orchestrates periodic somite formation.
